VEHICLE-"WHEEL.

SPECIFICATION forming part of Letters Patent N 0. 746,902, datedDecember 15, 1903.

Application filed June 23, 1902.

To aZZ whom it may concern:

Be it known that I, FRANK H. TURNER, a citizen of the United States ofAmerica, residing at Hartford, in the county ofHartford and State ofConnecticut, have invented certain new and useful Improvements inVehicle- Wheels, of which the following is a specifioation.

The object ofthe improvement is the pro-.

duction of novel and advantageous means whereby rubber tires, notablythose of the Dunlop type, may be successfully applied to Wheelsgenerally, including wooden wheels used on automobiles. This class oftires ref5 quires a support of peculiar contour to receive and supportthe peculiar form of the outer tube of the tire and hold it in placewhen the tire is inflated. The heavy work required of wheels used onautomobiles makes it desirable that a metal rim of some sort be used inconnection with wooden WhGGlS'WllGH such a wheel is used.

In the drawings, Figure 1 is a sectional view of a part of a Wheelembodying my improve- Figs. 2 and 3 are similar views of modifications.

The drawings show the outlines of the, improvement as applied to a wheelhaving a wooden felly. The letter A'denotes such a 0 wooden feliy, itsperiphery being substantially flat.

The metallic rim comprises an an n ular basetrough B, having the curvedflanges, D,and an annular rim face C. The edges of the an- Y nularbase-trough are by preference turned 4o--shown in Figs. 1 and 2 of thedrawings in connection with certain difiereuces of form. The rim-face O,which makes immediate contact with the rubber tire, has two parallelsides or Walls 0 and inward extension from the feet The rim-face isunited to the base-trough-as, for instance, by having the edges of therim-face embrace the edges of the base-trough to a degree which holdsthe two together. The rim-face C has its central 5o portion curvedinwardly to form a convex Serial No. 112,759. (No model.)

face which contacts with the bottom wall of the base-trough B, the outerends of which curved portion terminate in vertical walls lying paralleland engaging the side walls of the said trough, and then being curvedoutwardly in opposite directions to snugly embrace the adjacent portionsof the trough, as clearly illustrated. When the parts of this metallicrim are formed and assembled, it is dipped in a brazing solution, whichis permitted to flow to every point of con tact of the two pieces, thussecuring them. together as a practically integral structure. It will bereadily understood that the sides of the me: tallic rim, consideredasawhole, are strengthened by being made double at the upper part andalso, by preference, by making the duplicated parts semitubular inshape.

In lieu of having the portions E of the rimface C curved, as shown inFigs. 1 and 2 of the drawings, I may form the same straight, as at e.(Illustrated in Fig. 3 of the drawings.)

By making the inner periphery ofthe metallic rim (considered as a whole)substantially fiat it can be shrunk upon the flat face of the woodenfolly of a wheel in the ordinary manner, and it may be still furthersecured to the folly by additional means, if desired.

I claim as my invention- In combination with the rim, a base-troughmounted on said rim and comprising a bottom and vertically-disposed sidewalls, and an annular rim-face arranged in the said basetrough, andbeing provided with a convex central portion engaging the bottom of thesaid base-trough, the outer end of said convex portion extendingupwardly in parallel planes and engaging the side walls for the entirelength of the said vertically-disposed portion and then being bent overthe upper ends of the side walls of the said base-trough, substantiallyas described.

In testimony whereof I afiix my signature in presence of two witnesses.

FRANK H. TURNER.
